hi
I have posted in Linspire and am aware it may let you be root.
Freespire differs in that it tends to use sudo.
The explain is best done by this link
http://www.free-bees.co.uk/articles/freespire1/2/
2) and the freespire site docs tell you how to disable sudo if you wish and create a true root account and (for me) the use of su and real root password
submitted in case others try out freespire as well.
